Answer:
Step-by-step explanation:
Please, share the answer options next time.
1) f(x) = 2x^2– x – 6 is a quadratic function.
2) The coefficients of this polynomial are a = 2, b = -1 and c = -6
2) Its graph opens up.
3) The x-value of the axis of symmetry and the vertex is x = -b / (2a), which here comes out to x = -(-1) / [2(2)], or x = 1/4
4) the y coordinate of the vertex is f(1/4), or -6 1/8
5) The vertex is at (1/4, -6 1/8)
6) The y-intercept is at f(0): 2(0)^2 - 0 - 6 = -6 => (0, -6)
Answer:
x=2
Step-by-step explanation:
x+(2x)^2=18
1.) the answer would be D
2.) D
C=20+0.07(100)
C=20+7
C=27
3.) B
4y-10=22
+10 +10
4y=32
/4 /4
Y=8
4.)$132
60r+0.06(50r)=p
60(4)+0.06(50*4)=p
120+12=p
132=p
5.) $9.40
